Write a PHP program to print alphabet pattern 'N'

<?php
for ($row=0; $row<7; $row++)
{
  for ($column=0; $column<=7; $column++)
	{
  if ($column == 1 or $column == 5 or ($row == $column and $column != 0 and $column != 6))
            echo "*";    
        else  
            echo " ";     
	}        
  echo "\n";
}
?>

Sample Output:

 *   *                                                      
 *   *                                                      
 **  *                                                      
 * * *                                                      
 *  **                                                      
 *   *                                                      
 *   *
